Problems solved by technology

At present, the existing technology mainly determines the direction of the driving trajectory based on the coordinates of the starting point and the end point of the driving trajectory. This method cannot accurately determine the direction of the driving trajectory, which increases the difficulty of identifying the follow-up commonly used paths.

Abstract

The embodiment of the invention discloses a driving direction determination method and device, equipment and a storage medium. The method comprises the following steps: obtaining track data reported by a target vehicle, the method comprises the following steps: acquiring trajectory data, forming at least one corresponding driving trajectory based on the trajectory data, determining a fan-shaped area corresponding to each driving trajectory, determining a target trajectory point on the corresponding driving trajectory based on each fan-shaped area, and determining the driving direction of eachdriving trajectory according to the target trajectory point and the fan-shaped area corresponding to each driving trajectory. Compared with the prior art, the direction of the driving track is determined only according to the coordinates of the starting point and the terminal point of the driving track. According to the embodiment of the invention, the driving track of the target vehicle is subjected to region division to obtain the corresponding fan-shaped region, and the driving direction of the driving track is determined by utilizing the fan-shaped region and the target track point corresponding to each driving track, so that the determination precision of the driving direction is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular, to a method, device, device, and storage medium for determining a driving direction. Background technique [0002] With the development of Internet of Vehicles technology, more and more vehicle usage data is uploaded to the cloud, and user behavior is analyzed through big data. As the most direct manifestation of user behavior, the user's frequently used path is an important content of user behavior analysis. By identifying the user's frequently used path, it can understand the user's vehicle usage habits and provide users with personalized services. [0003] The identification of the user's common path first needs to determine the driving direction of the vehicle. Any two driving trajectories may be repeated only if they are traveling in the same direction, which provides a basis for the identification of common paths. At present, the existing technolo...
